I Cl. 259-72) 3 Claims.

This invention relates to a device for shaking and jiggling sacks andtheir contents so as to settle the contents to the bottom of the sackand compact them. Means are provided for supporting the sacks in openposition and means are also provided for continuously jarring the sackswhile being loaded so as to insure a full sack of I the product beingbagged. The invention is especially useful in machine sacking ofpotatoes and other vegetables, and particularly those vegetables and/orfruits which are generally shipped in long configurated sacks. Unlessthe sacks are uniformly loaded, their weights would obviously vary and,therefore, a truck load or group of so many twenty-five, fifty or onehundred pound sacks would not represent any true weight of a shipment.

One of the rincipal objects of this invention is to present a means forsacking vegetables and/or fruits wherein the sack is firmly supportedinopen position and continuously jiggled so as to allow complete fillingof the sack with any commodity.

Other objects, advantages and features of my invention will appear fromthe accompanying drawings, the subjoined detailed description, thepreamble of this specification, and the appended claims.

Applicant is about to illustrate and describe one of the forms of hisinvention in order to teach one how to make, use and vend the same, butit is to be understood that the drawings and description thereof are notto limit the invention in any sense whatsoever, except as limited by theappended claims.

In the drawings:

Fig. 1 shows the invention in side elevation.

Fig. 2 is a plan view of the invention.

Fig. 3 is an end view.

Fig. 4 is a sectional view taken substantially along the line 44 of Fig.1.

Fig. 5 is an elevational view of a portion of the invention, enlarged.

Fig. 6 is a plan view of the top portion of Fig. 5.

Fig. 7 is a sectional view taken substantially along the line II of-Fig.6.

The sacking device in the particular form illustrated comprises acentral portion 1 and elongated side portions or extensions 2 and 3.These side portions may be identical in construction. and are identicalin this form of the invention, but need not necessarily be identical.One of the side portions may be omitted entirely; The general structuralmembers and frame for the device are shown as comprising a plurality ofvertical wooden posts 5, G and I which support the central frame unit Iand the near ends of the side portions 2 and 3. The distal end of theside portion 2 is supported by the posts 8 and 9, and the distal end ofthe other side portion is supported by the posts I0 and II as shown. Thefront face of side portion 2 is covered by plyboard or heavy planks I2and the front face of the other side portion 3 is covered by plyboard orthe heavy planks I3. Across the front face of the central portion 1 arethe planks I4. are securely nailed or bolted to the rear side of thevarious posts. Along the rear of the device near the top thereof is acontinuous single plank I5 which is nailed to the posts 9, 5, 6 and II.To give lateral stability, each end of the device has the cross endplanks I6 and I1 nailed to their respective posts; at the centralportion are the cross planks I8 and I9 as shown.

For supporting various shafts etc., the front of the central. portionhas the spaced horizontal members 20 and 2| which are nailed to theposts 4 and I and at the rear similar horizontal members nailed to theposts 5 and 6.

At the lower front of the device is a platform 22 which extends alongthe entire length of the device and preferably very heavy planking towithstand bending stresses. This platform may be a single plank or madeup from a number of narrow planks. This platform is supported in amanner to allow it to be vibrated or jiggled longitudinally. At the endsand near the center of the platform are pivotally connected pairs ofhanger means or straps 23, the tops of which are pivoted to extensionelements 24, and their bottoms to the top of the platform. Theseextensions are supported by angle irons which have top horizontal bars25, vertical struts 26 and feet portions 21 which are bolted or screwedto a platformor to the floor of the building. The free ends of thehorizontal bars are bolted to their respective upright posts. Cleats 28are provided on the top surface of the platform to present a pluralityof areas for the bottoms of the sacks to be loaded. These cleats alsostrengthen the platform and tend to reduce the likelihood of warping.

A frame is provided on each right and left portion of the device to movewith the platform. Each one of these frames consists of end verticalposts 30 and 3| joined at their tops to a horizontal beam 32 from whichprotrude a plurality of spaced apart separators or heaters 33. Thesebeaters extend between the bags or sacks, when All these planks inplace, such as the sacks indicated at 34. Small feet 35 are formed atthe bottom of the posts 30 and 3| so that they can be securely bolted tothe top of the platform 22. When the platform is jiggled to shake thebottoms of the sacks, the heaters 33 shake the middle portions of thesacks.- The tops of the sacks are hung onto spaced apart hooks 36., seeEigs. 6 and 7, which are fixed to the inner .peripheryiot' thesackspreaderrloops in the frame unit 31. 'Each one of these unitsconsists of an angle iron 38 that is bolted to the top edge of the upperplank I2. Within the angle'is an elongated rod or pipe 39 supportedlatits ends in any suitable manner or bracket. so as to hold the pipespaced from the legs of the angle iron 38. Spaced at intervalslalong thepipe are a plurality of pivot elements 40*.whichhavesintegral sleeves 4|surrounding -the pipe. These elements have under sections thatengagerthe upper face of the horizontal legs of the angle iron 38 so asto limit t-he downward movementsof the elements lll.
